Abstract
The utility model provides a gas nozzle used on an ampoule encapsulating machine, which is composed of a joint, a spray head and a nozzle core arranged in the spray head. The nozzle core is provided with a main combustion hole; a plurality of combustion-supporting slots are uniformly distributed on the surface of the external circle of the main combustion hole; after matching with the nozzle core, the spray head forms a circle of combustion-supporting holes on the surrounding of the main combustion hole. A gas shunt chamber is formed between the surface of the external circle of the middle end of the nozzle core and the surface of the internal circle of the spray head; an ene gas shunt hole is arranged on the middle end of the nozzle core, which enables part of the gas to enter into the gas shunt chamber from a main channel.
Description
Technical field
The utility model relates to a kind of nozzle of burner, particularly a kind of combustion gas nozzle that is used on the ampule filling and sealing machine.
Background technology
In the production that ampoule filling seals, be extensive use of the fuel gas buring heating means and seal.The combustion gas nozzle of prior art is made up of joint and burning nozzle two parts, the through hole of the combustion gas through hole bore unanimity that to be or several draw from same passage, combustion flame is long, flame is thick, the ampule sealing place adds the branch that thermal-flame does not have power, wayward, cause that thus the outward appearance of sealing is not good and quality is also wayward.
Summary of the invention
The purpose of this utility model is to provide a kind of new combustion gas nozzle at the deficiencies in the prior art.
Technical solution of the present utility model is such: the combustion gas nozzle is by joint, shower nozzle and chew core and form, joint and shower nozzle adopt and are threaded, the tail end of shower nozzle is provided with sealing gasket, in shower nozzle, be provided with one and chew core, chew core and be provided with primary holes, chew the outer round surface of core primary holes and the endoporus of shower nozzle and adopt interference fit, on the outer round surface of primary holes, be evenly equipped with 8～16 combustion-supporting grooves, shower nozzle and chew core and cooperate after, border at primary holes has constituted a circle assistant burning hole by combustion-supporting groove, chew between the internal circular surfaces of the outer round surface of core middle-end and shower nozzle and form a combustion gas shunting chamber, be provided with one in the middle-end of chewing core and make the part combustion gas can enter right gas tap hole in the combustion gas shunting chamber from the main channel.
During use, combustion gas enters from joint, enters the burner core, and mainly by chewing the ejection of core primary holes, portion gas enters the shunting chamber by tap hole, from the ejection of auxilliary combustion groove.The primary holes combustion flame is clear, does not have yellow flame, firepower foot, flame stabilization.A circle flame that sprays from auxilliary combustion groove is even, a little less than the firepower, can guarantee ampule sealing place heating degree from central point outwards by by force to weak progressively transition, thereby guarantee seal quality.
Description of drawings
The combustion gas nozzle structural representation that accompanying drawing 1 provides for the utility model;
Accompanying drawing 2 is the right view of accompanying drawing 1;
Accompanying drawing 3 is for chewing the cored structure schematic diagram;
The specific embodiment
The combustion gas nozzle is made up of joint 1, shower nozzle 3, and joint 1 and shower nozzle 3 adopt and be threaded, and the tail end of shower nozzle 3 is provided with sealing gasket 2.In shower nozzle 3, be provided with one and chew core 4, chew core 4 and be provided with primary holes 8, the endoporus of the outer round surface of primary holes 8 and shower nozzle 3 adopts interference fit, be evenly equipped with 12 combustion-supporting grooves 7 on the outer round surface of primary holes 8, shower nozzle 3 and chew core 4 and cooperate after, constituted a circle assistant burning hole in the border of primary holes 8 by combustion-supporting groove 7.Chew between the internal circular surfaces of the outer round surface of core 4 middle-ends and shower nozzle 3 and form a combustion gas shunting chamber 5, be provided with one in the middle-end of chewing core 4 and make the part combustion gas can enter combustion gas tap hole 6 in the combustion gas shunting chamber 5 from the main channel.
